Portion of a pneumatic tire



FIG. 1 is a front perspective view of a portion of a pneumatic tire showing my new design.

FIG. 2 is a front view thereof; and,

FIG. 3 is a side view thereof.

In the drawings, the broken lines defining the sidewall, inner bead and the unclaimed sidewall depict environmental subject matter that forms no part of the claimed design. The dash-dot lines represent the peripheral boundary between the claimed tire tread and unclaimed sidewall.

The tread pattern is understood to repeat uniformly throughout the circumference of the tire, as shown schematically in solid lines. 

CLAIM The ornamental design for a portion of a pneumatic tire, as shown and described.
